镜像的制作分为三类
- 基础镜像
- 运行环境镜像
- app镜像
制作基础镜像
制作一个安装了扩展操作系统的基础镜像

推送到私有镜像仓库中:
docker build -t 192.168.3.27:8888/ops/os2 .
基于这个基础镜像os2制作jenkins的slave镜像

制作运行环境镜像
直接拖取已有的java运行环境镜像
docker pull java
docker tag java 192.168.3.27:8888/ops/java
制作tomcat镜像

制作app镜像
利用上面制作好的tomcat85镜像部署应用
FROM 192.168.3.27:8888/ops/tomcat85
ADD target/solo.war /tmp
RUN unzip -q /tmp/solo.war -d /usr/local/tomcat/webapps/ROOT
COPY deploy/docker-entrypoint.sh /usr/bin/docker-entrypoint.sh
ENTRYPOINT ["docker-entrypoint.sh"]
EXPOSE 8080

将应用部署到java运行环境的镜像
利用上面的java 镜像 部署我们的java应用
FROM 192.168.3.27:8888/ops/java
